Patent KR-20200099499-A (KR)
Inventor: NAM KI HYUN
IPC: C08F20/56
Filed: 2020-02-14
Abstract: The present invention relates to X-ray polyacrylamide specimen delivery and, more specifically, to the development of technology using polyacrylamide as a delivery substance in order to reduce the consumption of specimens on serial crystallography research. Since protein specimens do not interact with PAM, as a result, a protein crystal specimen also does not have a chemical reaction to PAM. Thus, for SFX research, every protein crystal specimen can use PAM as a delivery substance. Also, since X-ray background scattering does not occur, data which is supposed to find phasing from crystallography can provide an excellent signal/noise ratio (SNR), which can lead to an increase in an experiment success rate. Consequently, as compared to existing reported delivery substances, the application of various crystal specimens can be possible, and excellent data quality can be guaranteed.

Patent KR-20200138042-A (KR)
Inventor: FERIANZ THOMAS
IPC: H03K19/007
Filed: 2020-05-27
Abstract: Provided are circuits and devices for reliably holding a normally-off Gallium Nitride (GaN) power transistor, such as a Gate Injection Transistor (GIT), in a non-conducting state when a gate of the power transistor is not driven with an active (turn-on) control signal. This is accomplished by coupling a normally-on pulldown transistor between the gate and the source of the power transistor, such that the pulldown transistor shorts the gate to the source when the power transistor is not set for a conducting state. The pulldown transistor is preferably located on the same semiconductor die as, and in proximity to, the power transistor, to avoid spurious noise at the power transistor gate, which may unintentionally turn on the power transistor. A pulldown control circuit is coupled to the gate of the pulldown transistor and autonomously turns off the pulldown transistor when the power transistor is set to conduct.
